TO ALL 'WI-IOM IT MAY CONCERN:

Be it known that I, JESSE IIAVENS, of Auburn, in the county of Cayuga,and State of New York, have invented a new andV useful Improvement inFrames for Wood-Saws; and I do hereby declare that the following is afull, clear, and exact dcscription'of-the same, reference being had tothe annexed drawings, making part of this speeication, in which thesaine is shown elevation;

lhe following description will enable one skilled in the art toconstruct the saw-frame with my improvements. A is one end of the frame,and B the other. These pie-ees are respectively formed substantially asshown in the drawings, the piece B being extended below the saw to forma handle, to be grasped by one hand of the loperator. i Gis theAcross-brace, forming a fulcrum for the end pieces, which, being drawntogether above, ferm levers for stretching the saw-blade. This brace ismade of wood, as are also the pieces A and B. The brace is bifurcatedatene end, so that, while the lower part extends in a right line,parallel with the saw-blade, across the frame, from the piece A to thepiece B, the part C is curved upwards, resting against the upper p artof the end piece A. D is the dcv'icoer tightening the saw. It ispermanently attached to the end pieeeB by a neck and head, D, which isinsertedl in a longitudinal slot of corresponding form, cut in the endof the framepieee B, and it is secured by a collar, E, sliding neatly onto the end of the same. A screw-thread is out upon the projecting endot"the ,metallic piece D, which passes through holes in the piece C',and also in the piece A.I

A nut, D1, is screwed on to the piece D, inside of the frame-pieces Cand A, and a nut, D2, is screwed on the projecting end of the same, bywhich nuts the frame and saw F are held rigidly in place.

To tighten the saw, thev nut Dl must be loosened, and the rod D drawn upby lthe outside nut D2, the nut D1 being screwed down again, to confinethe frame, as'before.

What I claim as'niy invention, and desire te secure by Letters Patent,is-

1; A saw-frame, in which a bifurcated Awooden brace, C C', constructedin one piece, as described, is used, in combination witlrthe end pieces,substantially as described.

2. The piece D, constructed with a neck and head, D, and used incombination with the frame-*pieces A, B, andG, with which' it is united,substantially in the manner and for the purpose set forth.

In Atestimony whereoQI have signed myname to this specification in thepresence et" two subscribing witnesses..
